  24

   I 
  have 
  to 
  thaidc 
  Prof. 
  M'Intosh 
  for 
  giving 
  me 
  from 
  his 
  own 
  

   collection 
  a 
  typical 
  series 
  of 
  slides 
  of

  Family 
  Nephthydidae. 
  

   Genus 
  Nephthys, 
  Ouvier, 
  1817. 
  

  

  Nephthys 
  cceca, 
  O. 
  F. 
  Muller, 
  1776. 
  

  

  This 
  species 
  was 
  found 
  in 
  many 
  hauls, 
  and 
  only 
  in 
  one 
  

   (haul 
  11191, 
  at 
  Station 
  18 
  A) 
  were 
  there 
  not 
  more 
  than 
  one 
  

   brought 
  to 
  the 
  surface. 
  In 
  haul 
  187 
  forty-two 
  were 
  obtained 
  

   at 
  a 
  depth 
  between 
  545 
  and 
  788 
  m. 
  This 
  abundance 
  agrees, 
  

   as 
  far 
  as 
  the 
  North 
  Sea 
  is 
  concerned, 
  with 
  the 
  statement 
  in 
  

   the 
  Monograph 
  (1908, 
  vol. 
  ii. 
  part 
  i. 
  p. 
  10), 
  which 
  says 
  that 
  

   this 
  annelid 
  is 
  common 
  everywhere 
  around 
  the 
  shores 
  of 
  

   Britain. 
  

  

  Many 
  of 
  the 
  specimens 
  are 
  small, 
  but 
  some 
  are 
  of 
  moderate 
  

   size. 
  In 
  many 
  cases 
  the 
  lamellaj 
  of 
  the 
  feet 
  were 
  destroyed 
  

   by 
  being 
  scorched 
  by 
  the 
  fire, 
  while 
  the 
  specimens 
  themselves 
  

   were 
  rendered 
  hard 
  and 
  brittle. 
  On 
  the 
  feet 
  of 
  tliose 
  which 
  

   remained 
  unhurt 
  were 
  found 
  several 
  thecate 
  Infusoria 
  * 
  and 
  

   structures 
  which 
  resembled 
  minute 
  Loxosomce. 
  

  

  The 
  largest 
  specimen 
  had 
  148 
  segments, 
  but 
  in 
  some 
  of 
  

   the 
  smaller 
  ones 
  the 
  segments 
  numbered 
  from 
  60-80. 
  The 
  

   body-wall 
  was 
  very 
  muscular, 
  and 
  the 
  oblique 
  muscles 
  were 
  

   boldly 
  outlined. 
  

  

  The 
  gut 
  was 
  examined, 
  and 
  was 
  found 
  to 
  contain 
  diatoms, 
  

   mud, 
  sand-particles, 
  and 
  small 
  pieces 
  of 
  what 
  seemed 
  to 
  be 
  

   animal 
  tissue. 
  No 
  specimen 
  showed 
  an 
  extruded 
  proboscis.

  annelid
